Preventing fungal attack of freshly sawn lumber using cinnamon extracts
2007 - IRG/WP 07-30432
The potential for using cinnamon oil as an anti-mold and stain compound was investigated on ponderosa pine sapwood. Cinnamon oil was highly effective when used in ethanol, but its activity declined when it was mixed with only water. Attempts to enhance water solubility with surfactants improved solution stability, but had no apparent effect on biological activity. Further studies with other co-so...

The foreign exchange situation and fate of wood preservation in Nigeria
1989 - IRG/WP 3558
Up to about 15 years ago, wood utilization industry in Nigeria gave no serious thoughts to wood preservation. After this period however, as a result of escalated local demand for sawn timber, logs with wider sapwood and mainly of secondary tree species requiring protection of the sawn timber became dominant in the local timber scene. Preservatives both for protection in and out of ground contacts ...

Fungus cellar testing as an evaluation method for performance of treated timber in ground contact
2001 - IRG/WP 01-20227
A fungus cellar method for the accelerated evaluation of performance of treated wood in ground contact is described. The test soil comprised of sandy loam, vermiculite and Japanese horticulture soil "Kanumatsuchi" in a ratio of 6:2:2 by volume. The soil was inoculated with the dominant test fungus isolated with selective medium from decayed wood samples. Pairs of treated and untreated wood specime...

Role of Global Cooperation in Wood Protection for Conserving Forest Resources
2007 - IRG/WP 07-50249
The current uses of treated wood are discussed along with the emerging concerns for continued use of these products. The issues of new chemicals, treatments for wood based composites, migration of chemicals from treated wood, and the disposal of these products at the end of their useful life are all outlined. The potential for the IRG to serve as the focus for research discussion as well as coll...

Diffusion of a copper naphthenate/boron paste through Douglas fir heartwood
1991 - IRG/WP 3671
Groundline wraps are an important portion of the remedial treatment strategies for protecting utility poles in North America from surface decay. The compositions of these wraps have recently shifted away from pentachlorophenol and creosote to formulations containing copper naphthenate and boron. These formulations have not yet been extensively tested, although the chemicals have been used for many...

Changed permeability and surface properties of hornbeam wood due to its degradation by erosive strain of Phanerochaete chrysosporium
2004 - IRG/WP 04-40290
Specimens of hornbeam wood were submitted to a medium-term degradations by erosive fungus Phanerochaete chrysosporium. Biodegradations of specimens resulted in their apparent structural alterations, changes in permeability and increased intensity of interactions with polar liquids. Modified physical properties of biodegraded wood may significantly influence its penetration with polar media and che...

Wood Preservatives Science Issues: US EPA’s Perspective
2005 - IRG/WP 05-50224-2
The USEPA Office of Pesticide Programs (OPP), Antimicrobials Division (AD), regulates the use of chemicals registered as wood preservatives in the United States. An overview of the registration and re-registration process is presented. The wood preservatives data requirements include toxicological, human exposure, ecological, and environmental fate data. A detailed discussion of wood preservati...

Case histories involving attempts at identifying infestations, determining the source and controlling the Formosan subterranean termite in Atlanta, Georgia USA
2000 - IRG/WP 00-10342
The University of Georgia Department of Entomology and the Georgia State Department of Agriculture have been involved in identifying and working with Pest Control Operators and homeowners dealing with Formosan subterranean termite infestations in the Atlanta, Georgia metropolitan area since 1993. Our involvement with seven separate infestations is outlined in this paper in the form of case histori...

Serviceability of copper naphthenate-treated poles
2000 - IRG/WP 00-30214
Copper naphthenate-treated poles in service were inspected for deterioration, penetration, retention, and serviceability. The study to date has included poles in all hazard zones in the United States. Poles installed by 12 different utilities and eight different treating companies are included in the survey. Both southern pine and Douglas-fir poles and distribution and transmission poles are inclu...

Flow charts for termite and decay tests to determine the natural durability of Japanese cedar (Cryptomeria japonica D. Don)
2008 - IRG/WP 08-20385
This paper deals with the experimental flow charts that were used for determination the effects of fungal decay and termite attack on Sugi heartwood during the course of the study of “Comparative studies of natural durability of Japanese cedar (Cryptomeria japonica D. Don) among the geographic cultivate”, which was carried out by Usta et al (2006)....
